System OverviewDexcom Share remote monitoring system lets one person, the Sharer, transfer Dexcom G4 PLATINUM Continuous Glucose Monitoring information to another person, the Follower. Dexcom Share consists of the following components: Dexcom G4 PLATINUM System, including the Dexcom G4 PLATINUM Receiver with Share, the Sharer’s smart device, and optional Apple Watch as a secondary display, the Dexcom Share2 app, the Internet, the Follower’s smart device and optional Apple Watch as a secondary display, and the Dexcom Follow app. These Dexcom mobile apps can only be installed on an Apple iOS smart device.

When the Sharer’s receiver with Share has Share “On,” the receiver transfers glucose information using Bluetooth wireless technology to the Sharer’s smart device. The information then is sent to the Dexcom Share Cloud using either Wi-Fi or a cellular data plan. Lastly, the glucose


information is sent from the Dexcom Share Cloud to the Follower’s smart device using Wi-Fi or the Follower’s cellular data plan. Then if using an Apple Watch, the iPhone sends the Sharer’s sensor glucose information to the Apple Watch via Bluetooth and Wi-Fi as an optional secondary display.

Below is how Dexcom Share2 and Dexcom Follow Apps work with having the Dexcom Follower using an Apple Watch:


The Sharer, can also use an Apple Watch as a secondary display device for the Dexcom G4 PLATINUM with ShareCGM information:

For Apple Watch users, it is a secondary display, meaning the Apple Watch will only work if used with an iPhone.

The Sharer must have their smart device within Bluetooth range of their receiver in order to send data to their Follower or the system will not work. The following diagram

Sharer’s receiver and transmitter, iPhone and Apple Watch


Changing device settings on the iPhone may affect settings on the Apple Watch.

Conditions That Affect UseOnce Sharing is established, make sure the Share settings on the receiver, Sharer’s smart device and Follower’s smart device are not altered. Make sure the Sharer’s smart device and Follower’s smart device has enough battery power to maintain Sharing. Make sure the Sharer’s smart device has a Bluetooth and Internet connection in order to share data. Make sure the Follower’s smart device has an Internet connection in order to receive data from their Sharer. If using the Apple Watch, make sure there is a Bluetooth connection from your iPhone to your Apple Watch. Dexcom® recommends charging both the smart device and receiver with Share when Sharing. For Apple Watch users, Bluetooth and Wifi must be enabled on both the smart device and Apple Watch and the watch must be charged and on.

RisksDexcom Share is a feature of the Dexcom G4 PLATINUM


Continuous Glucose Monitoring (CGM) System. The main risks involved with using Dexcom Share are based on misunderstanding its purpose.

Remember that Dexcom Share2 is a secondary notification system, not a real-time remote monitoring system. With Dexcom Share, there are 3 distinct parts of glucose monitoring:1. Blood glucose meter - use this to make any

treatment decisions.2. Dexcom G4 PLATINUM CGM System - use the

Dexcom G4 PLATINUM CGM System to complement, but not replace, information obtained from the blood glucose meter. It detects glucose trends and tracks glucose patterns.

3. Dexcom Share2 - this is an optional add-on to the Dexcom G4 PLATINUM CGM System that can share glucose information and notifications with up to five (5) other people. Shared glucose information can add


another level of awareness.

Using the wrong glucose information for treatment decisions could lead to low or high glucose. Blood glucose values from a blood glucose meter may differ from the information displayed on Dexcom Follow app. All treatment decisions should be made using a blood glucose meter, not the glucose information displayed on the Dexcom Follow app. Followers who are concerned by notifications on the Dexcom Follow app should contact the Sharer’s and remind them to check their blood glucose with a blood glucose meter before driving a car or making any treatment decisions, such as taking insulin or eating fast-acting carbohydrates.

Sharers should not rely on Followers to notify them about low or high glucose. Any problems with the receiver, smart device, Bluetooth, wireless Internet connection, mobile data connection, Dexcom Share Cloud or not being in the communication range could cause data to not be shared with the Follower. In addition, if the Delay setting is too


long, the Follower might not be aware of glucose level changes in a reasonable time. Therefore, Dexcom Share should be used only to give a secondary level of awareness and should not be expected to always communicate and transfer sensor glucose information.

BenefitsPatients usually respond when their continuous glucose monitoring (CGM) systems alert them. However experts advise that an additional CGM alert to another person may be helpful in increasing the detection of low glucose or high glucose, especially at night. Dexcom Share enables this additional awareness, even when the Sharer and Follower are not in the same place.

Dexcom Share may provide improved quality of life and greater peace of mind to patients, their caregivers and their support team by allowing the Dexcom G4 PLATINUM System alerts, alarms and trend graphs to be checked remotely.


Indications For UseThe purpose of Dexcom Share Direct Secondary Displays is to notify another person, the Follower, of the patient’s Dexcom G4 PLATINUM Continuous Glucose Monitoring System sensor glucose information. The Secondary Displays is intended for providing secondary notification of a continuous glucose monitoring system and does not replace real time continuous glucose monitoring (G4 PLATINUM System) or standard home blood glucose monitoring.

The Dexcom Share Direct Secondary Displays is not intended to modify or analyze data received from the continuous glucose monitor system. Nor is it intended to instruct, or to transmit information to the continuous glucose monitor system. The Dexcom Share Direct Secondary Displays is not intended to serve as a replacement for a primary display device for a continuous glucose monitoring system. The Dexcom Share Direct


Secondary Displays is not intended to receive information directly from the sensor or transmitter of a continuous glucose monitoring system.

ContraindicationsDo not bring the Dexcom G4 PLATINUM Sensor, Transmitter, Receiver with Share, or smart device into a room containing medical equipment such

as Magnetic Resonance Imaging (MRI), Computed Tomography (CT), or diathermy. The system has not been tested with this equipment. Exposure to these types of equipment could heat and damage the devices so that they are unable to send or receive glucose information.

Important User InformationPlease review the indications, contraindications, warnings, precautions, cautions and other important information in the Dexcom G4 PLATINUM System User’s Guide. Dexcom Share is a feature of the Dexcom G4 PLATINUM System.

Warnings

Dosing decisions should not be made based on this device. The user should follow instructions on the continuous glucose monitoring system.

This device is not intended to replace self-monitoring practices advised by a physician.

Dexcom Share does not work alone. Dexcom Share does not replace the Dexcom G4 PLATINUM System and requires Share to be turned “On” on the Dexcom G4 PLATINUM Receiver with Share to communicate glucose information to the Follower. Dexcom Share is not compatible with any previous Dexcom CGM System or any other CGM device.


You cannot use Dexcom Share to make treatment decisions, such as how much insulin to take. Dexcom Share does not replace a blood glucose meter. Always use the values from a blood glucose meter for treatment decisions. Blood glucose values may differ from the sensor glucose information. Using the sensor glucose information for treatment decisions could lead to low or high blood glucose values.

PrecautionsDo not use Dexcom Share as the main source of CGM glucose trend information. Use the Dexcom G4 PLATINUM Receiver as the main device to track sensor glucose information, notifications and alarms. At times, the Sharer will be unable to share data using Dexcom Share, and the Follower might miss helping the Sharerin the event of low or high blood glucose values.

Do not rely solely on the Follower to alert the Sharer of low or high glucose events or other important information. At


times, the Follower may not receive data, and the Sharer will not be notified of this fact.

When using Dexcom Share, make sure the Dexcom G4 PLATINUM Receiver with Share has Share turned “On”. If not, the Sharer will be unable to share data, and the Follower might miss helping the Sharer in the event of low or high blood glucose values. You cannot use Dexcom Share unless there is a Bluetooth connection between the receiver with Share and the Sharer’s smart device. The Bluetooth range can vary and depends on the distance and obstructions between the receiver and the smart device. If the Sharer’s smart device does not have a connection or loses the connection, the Sharer will be unable to share data, and the Follower might miss helping the Sharer in the event of low or high blood glucose values.

Do not use Dexcom Share unless both the Sharer’s and Follower’s smart devices have active Internet connections, and for Apple Watch users, active Bluetooth connection,


in order to share data. If either the Sharer or the Follower does not have a connection, loses their connection, turns off the connection (“Airplane Mode”) or if smart device is in Do Not Disturb mode (if applicable), the Sharer will be unable to share data and the Follower might miss helping the Sharer in the event of low or high blood glucose values. To check this, make sure that the Follower’s smart device can receive text messages. Follow notifications and text messages work by a similar process on a smart device or Apple Watch.

For the Apple Watch, make sure you follow the Apple guidelines to receive glucose information and notification on the watch (see Apple Watch User Guide).

Make sure the Sharer’s and Follower’s smart device or Apple Watch have charged batteries or are connected to electrical outlets. If the smart device or Apple Watch shuts down due to low battery, the patient will be unable to share data, and the Follower might miss helping the Sharer in the


event of low or high blood glucose values.

If your Apple Watch runs out of battery as a Sharer, use your iPhone and/or receiver. In addition for Apple Watch users, Bluetooth and Wi-Fi must be enabled on both the iPhone and Apple Watch. All smart devices must be charged and turned on.

If the Sharer’s smart device is powered off or restarted, make sure the Dexcom Share2 app is reopened after the smart device is turned back on in order to resume sharing. If the Dexcom Share2 app is not reopened, the patient will be unable to share data, and the Follower might miss helping the Sharer in the event of low or high blood glucose values.

Do not turn off system sounds in the Follower’s smart device or Apple Watch at any time that he or she wants Follow notifications to be heard. The smart device or Apple Watch settings override the Dexcom Follow app, and all notifications will be silent even if the Follower has selected


a Dexcom Follow app notification sound. If the smart device or Apple Watch is on vibrate, the Dexcom Follow app notifications will only vibrate.

Check the delay settings on the Sharer’s smart device to make sure they are not too long. The Follower will not receive notifications until after the time period in the delay has passed, and the Follower might miss helping the Sharer in the event of low or high blood glucose values if the delay is too long.

The Sharer should not choose to “Not Share” with the Follower at any time when he or she wants the Follower to get notifications. During the time the Sharer chooses to “Not Share”, the Follower will not receive notifications and might miss helping the Sharer in the event of low or high blood glucose values.

Check the Dexcom Follow app’s trend graph if the Follower’s smart device has been off or if there is no data connection (e.g., Internet/Wi-Fi or mobile data


service/3G/4G/LTE is lost, connection is turned off in Airplane Mode, or smart device smart device or Apple Watch if applicable, is placed in Do Not Disturb mode. When the smart device or Apple Watch is turned back on, the Follower will only receive the most recent notification and might miss helping the Sharer in the event of prior low or high blood glucose values.

Sharers and Followers should check whether their cellular service carriers support voice and data at the same time (simultaneous voice and data). If their carriers do not support simultaneous voice and data, the Dexcom Share2 app may not be able to share glucose readings and the Dexcom Follow app may not be able to receive notifications or glucose readings during phone calls. Dexcom Share will resume sharing after the phone call has ended, and the Follower will receive any waiting notifications after the phone call has ended.


Jailbroken Smart DevicesDexcom requires Sharers and Followers to not use Dexcom Share apps on a jailbroken smart device or Apple Watch. A jailbroken smart device does not offer a reliable means to use Dexcom Share. Jailbroken smart devices present an unacceptable level of security and inaccuracy risk to the user and are not authorized to use Dexcom Share.

User AgreementYour use of the Dexcom Share System is subject to the terms of the most current Dexcom Share End User License Agreement posted at www.dexcom.com/share2, and the Dexcom Share Privacy Policy posted at www.dexcom.com/share2, as those documents are updated from time to time according to their terms.

Types of Glucose NotificationsA glucose notification is a visual message saying “Glucose notification from [Sharer’s name]” that appears on the screen of the Follower’s smart device or Apple Watch. The notification may also include a sound, depending on the settings on smart device or Apple Watch. The following table describes the different causes of notifications the Follower can choose to receive from their Sharer.


Notification Cause

Definition

LowNotification

Sharer’s sensor glucose reading was at or below the Follower’s set glucose reading for the low notification. Follower will be sent a notification once the delay setting is met.

Urgent LowNotification

Sharer’s sensor glucose reading was at or below the Follower’s set glucose reading for the urgent low notification. A notification is immediately sent to the Follower. There is no delay setting.

High Notification

Sharer’s sensor glucose reading was at or above the Follower’s set glucose reading for the high notification. Follower will be sent a notification once the delay setting is met.

Changing Glucose NotificationsThe Follower can choose when low, urgent low, and high notifications are sent. Initially, the Sharer sends


recommended notification settings with the FollowInvitation e-mail. The notifications of the Sharer’s glucose information are initially based on these settings. However, the Follower may change these notification settings:1. Glucose level - Glucose reading that initiates a

notification to the Follower’ssmart device.2. Delay - Time delay between when a glucose reading

condition is met and when the Follower’s smart device or Apple Watch is sent a notification if the glucose reading condition continues to be met.

3. Sounds - The sounds the Follower’s smart device or Apple Watch makes when receiving notifications.

4. Repeat - Repeats the notifications after a chosen period of time if the glucose reading conditions have not improved. This option is not available for urgent low notifications, which automatically repeat every 30 minutes.

If using the Apple Watch, notifications may appear on the


watch with sound and haptic feedback (gentle tap on the wrist). The strength of the haptic feedback can be adjusted to desired level. In addition, if you put your hand over the Apple Watch, the notification will go silent. See the Apple Watch user guide for more information.

111Technical Information

CHAPTER SIXTechnical Information


Technical InformationRecommended Separation Distances Between Portable and Mobile RF Communications Equipment and the Dexcom G4 PLATINUM Receiver with ShareThe receiver with Share is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the receiver with Share can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the receiver with Share as recommended in the Dexcom G4 PLATINUM System User’s Guide, according to the maximum output power of the communications equipment. Portable and mobile RF equipment include: baby monitors, Bluetooth wireless headsets, wireless routers, microwave ovens, laptops with internal Wi-Fi adapters, GSM cell phones, RFID scanners and hand-held security metal detector often used by security screeners.


Radio Frequency (RF) Communication Specifications• Receiver with Share to smart device Wireless Link o Protocol: Bluetooth Low Energy (BLE, or

Bluetooth v4.0); o Operating Distance: up to 15 feet (4.5 meters) o Output Power: 0dBm o Frequency: 2.4 GHz Industrial, Scientific, and Medical

(ISM) band o Modulation: Gaussian frequency-shift keying• Sharer smart device to Dexcom Share Cloud: o RF Operating Frequencies: Wi-Fi (802.11n) or cellular

Internet connection • Dexcom Share Cloud to Dexcom Follower smart device: o RF Operating Frequencies Wi-Fi (802.11n) or cellular

Internet connection

Wireless Technology Requirements for SharersSharer must install the Dexcom Share2 app on a compatible iPhone 4S (or later model), Pad 3 (or later


model) or iPod touch 5th Generation (or later model) or i which contains a BLE (Bluetooth 4.0) Radio, and have a working Internet connection through a Wi-Fi or cellular data network.

Wireless Technology Requirements for FollowersFollowers must install the Dexcom Follow app on a compatible iPhone 4 (or later model), iPad 2 (or later model) or iPod touch 5th Generation (or later model) and have a working Internet connection through a Wi-Fi or cellular data network.

Quality of ServiceFor the Dexcom Share to operate, the Dexcom G4 PLATINUM Receiver with Share must have Share turned “On” in the Settings.

The Dexcom G4 PLATINUM Receiver with Share communicates with the Sharer smart device using a BLE link. BLE technology uses what is called “adaptive


frequency hopping” as the method for co-existence with other wireless devices sharing the 2.4 GHz Industrial, Scientific, and Medical (ISM) band.

A valid Internet connection is required for both the Sharer’s and Follower’ssmart device. Adherence to the following guidelines will result in a consistent and reliable quality of service (QoS): • Ensure the Sharer’s smart device has a working

Internet connection via Wi-Fi or cellular network • Ensure the Follower’s smart device has a working

Internet connection via Wi-Fi or cellular network • Ensure the Sharer’s smart device is within 15 feet of

the Dexcom G4 PLATINUM Receiver with Share

The risks associated with QoS are mitigated because the data is requested from the Dexcom CGM Receiver every five minutes. In addition, as noted in the User Manual, the Dexcom Share System is a secondary notification feature and is not intended for the replacement of the


real-time continuous monitoring function of the Dexcom G4 PLATINUM System.

Data SecurityThe Dexcom G4 PLATINUM Receiver with Share is designed to accept Bluetooth pairing requests for connection only from authorized users of ismart devices that are using the Dexcom Share2 app. Data security and confidentiality are ensured by using an encrypted Bluetooth low energy communication link and an authentication pairing process that prevents unauthorized users from connecting to or eavesdropping on the Dexcom G4 PLATINUM Receiver with Share. During pairing, users are required to enter the serial number of the receiver. Be sure to safeguard the serial number of your receiver to prevent unauthorized users from pairing to your receiver. Cyclic redundancy checks are used in the error checking process to prevent the system from using corrupted data.

The Dexcom Share Cloud ensures data security through


several redundant means. It is designed to only accept data from authorized Dexcom applications and allows data to be read only by authorized Followers using the Dexcom Follow app. All data are encrypted using secure HTTPS communication channels and the Cloud is authenticated with certificates. Data integrity is ensured by using cyclic redundancy checks in the error checking process to prevent the system from using corrupted data.
